The freshness of the exposed por-tion of the drift along Fourmile, Sevenmile, and Indian creeks leads thewriter to consider it of the same age as the moraine. The shells and twigsi-eported above, which were pumped from sands beneath the till near themouth of Fourmile Creek, may be of interglacial age, and mark the linebetween the Wisconsin and the earlier drift sheet.
